myedgeisbroken Posted January 26, 2023 Report Share Posted January 26, 2023 hello i have a 2010 edge awd that the viscous coupler is locked up on. Could not source a coupler but im finding lots of used RDUs. I read a post that to install a replacement viscous coupler or RDU that the computer has to be updated with the new tag numbers. What numbers am i looking for? Quote Link to comment Share on other sites More sharing options...
